SPECIFICATION forming part of Letters Patent N 0. 606,165, dated June 21, 1898.

Application filed June 2 8 l 8 9 '7.

T0 au whom, it may concern:

Be it known that we, HENRY R. GREGORY and RICHARD H. BATTON, citizens of the United States, residing at Prescott, inthe county of Adams and State of Iowa, have invented a new and useful Straw-Stacker for Threshing-Machines, of which the following is a speciication.

This invention relates to that class of straw-stackers that are designed to be attached to and operated by power derived from the threshing-machine; and our object is to provide improved means for supporting the attachment so that it may be easily and quickly leveled up when the machine is in position for use, so that it may loe advanced over ordinary roads easily and conveniently or be entirely carried bythe threshing-machine.

Figure 1 shows a side elevation of the complete device applied to the rear end portion of a threshing-machine. Fig. 2 shows a rear end elevation of the same. Fig. 3 shows a detail sectional view through the line 3 3 of Fig. 4, and Fig. 4 shows a top or pl'an view of the turn-table of the attachment and connected parts. y A

Referring to the accompanying drawings, the reference-numeral 10 is used to indicate the body of the threshenand l11 the strawconveying extension on the rear end thereof.

12 indicates a belt-wheel fiXed'to a shaft 13, which is driven by the mechanism on the inside of the threshing-machine and from which power is transmitted to operate the endless conveyer of the stacker.

The reference-numeral 14 is u sed to indicate the stackerframe hinged to the inachine-frame by means of the plates 15 to be capable of a vertical movement. Rods 16, having hooks at their ends, are` provided to enter eyes on the rear end of the. machineframe and at the sides of vthe frame 14. These rods may also be used in supporting the frame 14 in an elevated position.' At the rear end of the frame 14 a caster-wheel17 is slidingly mounted in bearings 18.0n the rear of the frame 14. Set-screws are provided, whereby Serial No. 642,765. (No model.)

.vious that the said stacker-frame will be held in alinement with the' threshing-machine 55 frame at all times, and,further, by supporting the rear end of this stacker-frame on a caster-wheel which is attached to the central portion of the stacker-frame at its rear end it is obvious that when the said caster-wheel 6o passes over a projection on the road-surface the entire rear end of the stacker-frame will be raised and lowered and there will be no side strains upon the hinges, such as would be occasioned if there were two supportingwheels for the rear end of the stacker-frame at the opposite sides thereof and in the event of one of these passing over a projection on thel road-surface.' Furthermore, when the machine is placed in4 position for use the 7o stacker-frame may be readily and quickly leveled up by adj Listing the position of the upright of the caster-wheel relative to the frame of the stacker, thus obviating the loss of time and annoyance incident to blocking up each Wheel where more than one supporting-wheel is provided for the rear end of the stackerframe. v

' Mounted upon the top of the frame 14 is a circular' track 19, having a central upturned 8o Iflange 20, and 21 indicates a circular table slidingly mounted upon the track 19 and held in'place by means of lthe guide-loops 22, so that it will be capable of' a partial rotation upon the track, but will be prevented from 85 moving in another direction. Upon this r0- tatalole table 21 are two supports 23, and upon these supports a cross-piece 24 isl mounted, and this cross-piece 24 is arranged to receive and support the brackets 25, which in turn are 9o iiXedto the lower section 26 of the endlessconveyer chute, which will be hereinafter described.

27 indicates a shaft rotatably mounted in the supports 23, directly below the cross-piece 24 and parallel therewith. On its outer end is a sprocket-wheel 28,andA near its central portion is a bevel gear-wheel 29, the function of which will be made clear hereinafter.

The reference-numeral 30 isused to indicate a shaft to extend vertically and mounted in the bearing-boxes 31, which same are arranged concentrically of the track 19. To the upper end of this shaft 30 I have fixed a gearing device having a bevel-gear 32 on its top surface and a similar bevel-gear 33 on its under surface. This gear 32 is held in mesh with the bevel gear-wheel 29, and the gear 33 on the under surface is meshed with a gearwheel 34, which in turn is mounted upon a shaft 35, which is supported in the frame 14 and which is provided with a belt-wheel 36 on its outer end. This belt-wheel 36 is connected by meansof the belt 37 with the beltwheel 12, hereinbefore described, and it is obvious that during the rotation of the threshing mechanism the shaft 35 will be rotated, the bevel-gears 34, 33, 32, and 29 will be rotated, and the sprocket 28 operated thereby, and it is obvious, further, that this motion of the shaft 27, to which the bevel-gear 29 inl the sprocket 28 is fixed, will continue irrespective of the variation of its angle from a position parallel with the shaft 35. In other words, the sprocket-wheel 28 will continue tol rotate so long as the belt-wheel 12 is rotated,

no matter in what .position the turn-table of the device is placed.

The reference-numeral 38 is used to indii cate the upper section of the endless-conveyer frame, which is connected by means of the l hinge 39 with the lower section in such a manner that the upper section may fold for-` wardly over the top of the lower section to occupy a minimum of space. These sections are held in alinement when in use by means of a rod 40, which is passed through the plates 41 and 42, that are fixed to thesides of the conveyer-frame and are provided with` openings for the reception of the said rod.`

a sprocket-wheel 44 on its outer end, and at` the upper end ofthe conveyer-frame is a shaft 45, also rotatably mounted.

Belt-wheels 4G are placed upon the said` shafts 43 and 45, and in use it is designed to pass the endless conveyer over these beltwheels. This endless conveyer, however, is

not shown in the accompanying drawings. A sprocket-chain 47 is passed over the sprockets 28 and 44, and hence the shaft 43 of the endless conveyer will be constantly rotated during the rotation of the belt-wheel 12, and itl is obvious, further, that turning the endless` conveyer frame in a horizontal plane will not interfere with the driving of this shaft 43 by means of the chain 47, and, furthermore, the

endless-c onveyer frame maybe raised and lowered without interfering with this driving,

` for the reason that the pivotal point of the frame is substantially concentric with the shaft 27. We have provided means for raising and lowering this endless conveyer as follows: The reference-numeral 48 is used to indicate a derrick pivotally attached to the top of the threshing-machine to a shaft 49, which is mounted thereon. At the upper end of the pivot a pulley 50 is attached, and 51 indicates a rope attached to the upper end portion of the endless-conveyer frame, passed vover the pulley 50, and wound upon the shaft 49. A crank 52 and ratchet-wheel 53 are fixed to this shaft 49, and a gravity-pawl 54 is pivoted to the top of the machine-frame to engage the said ratchet-Wheel. Hence when the crank 52 is rotated the rope 51 will be wound upon the shaft 49 and thepulley and ratchet-wheel 53 and 54 will prevent the rope from unwinding. This, obviously, will elevate the endless-conveyer frame. A guy-rope 55 is attached to the derrick 48 and to a stationary support on the machine-frame.

. In practical use it is obvious that thc straw as it is discharged from the extension 11 on the rear end of the threshing-machine will fall upon the endless-conveyer frame at a point directly above its pivotal point, and hence no matter in which direction `the endless-conveyer `frame is extended the straw will fall upon the frame. It is obvious, further, that during the operation of the threshing-machine the shaft 43 of the endless conveyer will be operated through the mechanism described, no matter at what angle the endless-conveyer frame is extended relative to the threshing-machine. Furthermore, the endless-conveyer frame may be readily and easily swung laterally and may also be raised and lowered without stopping the operation of the endless conveyer. Furthermore, the whole device is in the nature of an attachment that may be placed upon any threshingmachine, and when being advanced over a road the weight of the stacker attachment is supported by its own caster-wheel and the endless-conveyer frame may be folded up", so as to occupy a minimum of space.

It is to be understood that therods 16 may be detached from the frame 14, and in practical use these rods are usually detached when passing over ordinary roads, so that the rear end of the frame 14 may move vertically. When the rods 16 are connected with the frame 14, the caster-wheel is usually elevated, so that it will not engage obstacles on the road-surface.

Having thus described the construction, arrangement, and function of each separate feature of the stacker attachment, what we claim as our invention, and desire to secure lpy Letters Patent of the United States there- IOO The combin ation with a threshing-machine, of a stacker-frame hinged thereto in such a manner as to be capable of a vertical movement and all lateral movement be prevented, and so that the stacker-frame is held in alinement With the threshing-machine frame at all times, a caster-Wheel having an upright connected therewith, bearings on the rear central portion of the stacker-frame designed to Io receive said upright and permit it to be adj usted vertically therein, clamping devices for fixing the upright in any desirable position relative to the said bearing, and strawstacking mechanism on said frame, substantially as and for the purposes stated.
